WATER-H'EATING- ATTACHMENT FOR STOVE-PIPES.

The Schedule referred to Ln these Letten Patent and making part of the same.

To all whmn it may concern Be it known that L'NATHANIEL Rowe, of Emmitsbnrg, in the county of Frederick and State of Maryland, have invented certain Improvements in Stove-Pipes; and I do'hereby declare that the following is a. full, clear, and exact description thereof', ref-- erence being had to the annexed drawings making part of this specification, in which- Figure 1 is a vertical section of a joint of pipe, having my improvement connected therewith, showing the water-space for the water between the two cylinders, and the pipes for connectingwith it a tank or reservoir for the water to be heated.

Corresponding letters refer to corresponding parts.

This invention relates to an improvement in Stove- Pipes, by which any one section or joint of such pipes may be converted into a heater for heating water for any purpose', and

It consists in providing a section or joint of such pipe with a conduit or passage through which water may circulate and be heated by the gases which cscape from the burning fuel on their passage to the chimney or line which conducts them to the atmosphere, as will be more fully explained hereinafter.

It is well known to persons familiar with stoves that aconsiderable amount of the heat resulting from the fuel burned therein is lost by being passed off through the pipe, which, if properly utilized, would heat a large amount of water for cooking and for other purposes.

My object in the present invention is to provide a means of rendering available the heat thus lost.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A in the drawings refers to a section or joint of a stove-pipe, which is enlarged throughout the greater portion of its length to enable it to receive the water conduit, as shown in the drawings.

The reduced portions A of this section are to receive the ordinary stove-pipe, and may be of any size required.

B refers to a space for water which is formed by extending the reduced portions A through the larger portion A, and forming a tight joint at the heads thereof.

B refers to a series of small pipes which pass through the 4portion A transversely and extend beyoud its surface for some distance, but not far enough to come in contact with the outer shell A.

The ends of these pipesA communicate with the space B, so that the water may flow freely through them, and be heated by the escaping gases within the portion A of the pipe.

O and O are pipes leading respectivelyfrom the upper and lower ends of the water-space B to and connect with a water-reservoir, C2, which latter may be arranged at any convenient point near the stove.

The Voperation of this device will be as follows: Y

The section of 'the pipe having been constructed as' show n in the drawings, it is to be placed upon the stove, and should generally be arranged to constitute the first joint of the pipe. Vv'hen thus placed, a pipe, C, is to be connected with the lower end of the circulating space, from which point it is to extend to and be connccted with the water-reservoir at or near its bottom, while to the upper end of said space B there is to be connected another pipe G, which is to extend to and deliver the water to the reservoir at some point above that where the pipe C takes it from such reservoir.

When the parts have been constructed and arranged as above described, and a fire has been kindled in the stove with which they are to be nscd, and water has been supplied tothe reservoir, it will fill the wa ter-space B, and, as it becomes heated by the escaping gases, the water will rise in the space and pass out thro'ugh the pipe C into the reservoir, and the cooler water from snchreservoir will pass in through the pipe C and take the place of that expelled by the heat, and thus a continuous circulation of the water will be kept up as long as the heat in the stove-pipe is sufficient for that purpose.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-

'The combination and arrangement of the stovepipc section A, constructed with a water-space, B, and circulating-pipes B', the pipes C and C and the water reservoir O2, substantially as set forth.

In testimony whereof, I have signed my name to this speciiication, in the presence of two subscribing witnesses.
